The advantage of direct drive: compared with the previously adopts the design scheme of mechanical protractor, direct drive scheme superior in the following aspects: 1. Repeatability is better with repetitive error less than 1 framework DDR arc seconds, much better than mechanical protractor. 2. Performance will not decline as time direct drive system performance, accuracy and repeatability of not like mechanical protractor decreases over time. If the mechanical protractor, over a period of time after the parts will wear, decreased accuracy and repeatable. 3. Stop quickly if the process error, direct drive system will stop quickly. Mechanical protractor requires several cycles to stop, so easy to damage the processing parts and machine. 4. Significantly reduced if the mechanical noise protractor, the noise is very big, two people need to shout to hear each other. Using a framework DDR, barely hear it the voice of the operation. 5. DDR easily change the path using a framework, it is easy to change the transposition Angle, speed, acceleration and movement parameters, such as idle time. Mechanical protractor does not support flexible movement. 6. Adding value compared with alternative mechanical protractor, framed DDR prices very attractive. If you consider the other advantages, there is no doubt that have a DDR framework is the better choice. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
